PATTERNS OF INTERSPECIFIC ASSOCIATIONS IN PLANT PARASITIC NEMATODES OF SUGARCANE ECOSYSTEMS

Abstract

Interspecific association analysis of four nematode species in sugarcane fields of India revealed that Pratylenchus zeae showed negative association with Hoplolaimus indicus and Tylenchorhynchus annulatus and a positive association with Helicotylenchus dihystera. Feeding site and feeding habit are the primary factors responsible for association of the two nematodes.
